Players alternate, each turn selecting a pit on the home side.
The pit's seeds are sown counterclockwise, skipping the original pit.

If the seed last sown lands on an opponent's pit with two or three
seeds, those seeds are captured. Then, if the next-to-last seed also
landed on an opponent's pit with two or three seeds, they are
captured. And so on. But if this would leave no seeds for opponent,
none are captured.

If all opponent pits are empty, you must sow a seed on
the opponent's side.
